Here's why tens of thousands of teachers are protesting in South Korea

Educational Reform: Teachers in South Korea have historically protested against various educational reforms proposed by the government. These reforms often include changes to the curriculum, testing systems, and school policies. Teachers may protest when they believe these changes could negatively impact students' well-being or the quality of education.

Labor Issues: Teachers, like any other professional group, may go on strike or protest when they have labor-related issues. This could include concerns about salaries, working conditions, and job security.

Standardized Testing: South Korea places a strong emphasis on standardized testing, such as the College Scholastic Ability Test (CSAT). Teachers and students alike have sometimes protested against the high-stakes nature of these exams and the pressure they place on students.

Inequality in Education: There have been protests over perceived inequality in the South Korean education system, particularly related to the availability of resources and opportunities in different regions. Teachers may demand more equitable distribution of educational resources.

Government Policies: Protests can also be directed at broader government policies. Teachers may take to the streets if they believe that government decisions are negatively affecting education or the teaching profession.

COVID-19 Impact: The COVID-19 pandemic significantly disrupted education worldwide. Teachers may have protested for safer working conditions, changes in teaching methods, or against government decisions related to the pandemic's impact on education.

It's important to note that the specific reasons for teacher protests in South Korea can vary over time and may depend on the policies and decisions of the government in power.
